Application filed December 10, 1912. Serial No. 735,902.

To all whom it may concern:

Be it known that I, WILLIAM Rosa, a subject of the King of Great -Ireland, of Albion Works, Gainsborough, 1n the county of Lincoln, England, have invented new and useful Improvements in Apparatus for Filling Bags or the like, of which the following is a specification.

This invention relates to apparatus for packeting tea, tobacco, or other materials, (such for instance as tapioca,- coffee, dry soap, and the like,) and its object is to provide an improved and very eflicient machine for such purpose.

The apparatus according to this invention is especially intended for packeting ma terials in bags, or containers, made by apparatus in accordance with my application for British Letters Patent No. 3149, A. D. 1912, but it can be used for packeting in bags, or

containers, otherwise made,

I will describe the invention with reference to the accompanying drawings, but I do not limit myself to the precise construction illustrated.

Figures 1 and 2 are side elevations of an apparatus constructed in accordance with my invention. Fig. 3 is a plan of Flg. 1.

Fig. 1 is an end view looking in the direction of the arrow A Fig. 3. Fig. 5 is a plan showing the main driving gear and the packet-wheel driving gear. Figs. 6, 7, 8 and 9 are detail views drawn to an enlarged scale of the mechanism for feeding the bags to the packet wheel. Figs. 9 to 15 both inclusive are detail views of the filling mechanism.

The bags or containers (which for brevity I will presume to be paper bags) are fed to the apparatus of the present invention in any suitable manner, the said bags being delivered to a transfer device 1 (Figs. 1, 2, 3, 6, 7, 8 and 9) integral with, or secured to, an arm 2 which is mounted to a shaft 3 having a segmental rack 41 at its opposite end (Figs. 1,2, 3 and i). The segmental rack 4 (Figs. 1 and 2) is adapted to mesh with a similar rack 5 carried by an arm 6 loose on a pivot pin 7 carried by the framework 8 of the apparatus. The arm 6 is connected in any suitable manner to a rod 9 which is actuated from the auxiliary driving shaft 10 against the action of a spring 18 (see Fig. 4) by means of a cam 11 and bell crank lever 12 so that the transfer channel 1 carrying a bag can be par- Britain and I tially rotated through an angle of or about 90 so as to bring the transfer channel and bag contained therein from a horizontal position to a vertical position, in which position the bag is delivered into a box or receptacle 13 carried by a wheel or disk 17 hereinafter referred to as the packet Wheel. When the bag is in the vertical position it abuts against a fixed plate or support 14 carried by a bracket 15 secured to the framework 8 of the apparatus. When the bag is in the vertical position, it is inclosed on all sides within a tube or guide which is partly formed by the transfer channel 1 and the aforesaid fixed plate or support 1 1. The auxiliary driving shaft 10 is driven by gear wheels 22, 23 and 256 (see Fig. 5) from the main driving shaft sleeve 16. On a horizontal plate underneath and in close proximity to the said tube or guide formed by ihetransfer channel 1 and the fixed plate or support 14 is situated the packet Wheel or disk 17 (Figs. 1, 2, 3, 4, 5) which carries any suitable number of boxes or receptacles 13 (say for example twelve) and has intermittent movements of partial rotation imparted thereto.

When I use a bag-forming machine in accordance with the bag-forming machine described in the aforesaid British application- No. 3149/12 in combination with a packeting apparatus in accordance with my present invention, I prefer that the intermittent partial rotations of the wheel of the bagforming machine and of the packet wheel of the packeting apparatus shall take place alternately, that is to say, that a partial rotation of the first mentioned wheel shall not 'occur simultaneously with a partial rotation of the packet wheel, as then the power required to perform the tWo partial rotations is more efliciently utilized. I do not however limit myself to this mode of operating as I may cause both wheels to move simultaneously if desired.

The aforesaid boxes, or receptacles, 13, which are carried by the packet wheel 17, consist, in the case of rectangular bags of four complete sides, but are open at their upper ends, the outer side however being preferably formed by a plate 19 (see Figs. 1, 2, 4, 5, 6, 7, 8 and 9), the other three sides being preferably formed in one piece or casting 20 secured to the packet wheel 17. The construction of the aforesaid boxes, or receptacles, is such that when the plate 19 is secured to the casting 20, a complete openended box is formed. The boxes, or receptacles, carried by the packet wheel 17 are of a size and shape correspondingto that of the packets to be made, but the sides are shorter in length than the length of the bags, as shown in Figs. 6, 7, 8 and 9.

The packet wheel 17 is rotated by any suitable means, such for example as shown in Fig. 5, in which 16 is the driving sleeve on the gudgeon 21, the said sleeve 16 having secured thereto a gear wheel 22. The packet-wheel 17 is intermittently rotated through the spur gearing 22, 23, auxiliary drivin shaft 24 and bevel gear wheel 25, 26. T e bevel gear wheel 26 is mounted on a sleeve 27 (Fig. 2) carried by the short shaft 28. Mounted'on the lower end of the sleeve 27 is a spur wheel 29, or a disk, provided with a pivot pin 30 carrying a roller 31 which engages in succession with each of a series of slots 32 formed in the disk 33 carried by a sleeve 34 embracing a shaft 65, and to which sleeve is secured the packet wheel 17. It is to be understood that the number of slots 32 in the aforesaid wheel or disk correspond to the number of boxes or receptacles 13 carried by the packet wheel 17. In this arrangement it will be seen that the packet-wheel and the boxes, or receptacles, 13 are intermittently rotated so as to-permit of the required operations being performed on the bags.

The packet-wheel 17 as shown in Fig. 5 is locked from rotation by means of a bellcrank lever having three arms 35, 36 and 37 carrying rollers 38, 39, 40, the roller 40 of arm 37 is adapted to engage with one of the slots 32 when the roller 39 of arm 36 is clear of its respective slot. This arm 37 is positively operated in one direction to engage one of the slots 32 when it is necessary to lock the packet-wheel and when it is necessary to release the packet-wheel to permit of its being partially rotated, the arm 37 is positively operated in the other direction. The motion of the two arms 35, 36, is obtained from two peripheral cams 41, 42, as shown in Figs. 2, 4 and 5, which cams are so mounted on the sleeve 27 that the two arms are caused to mutually follow each'other. That is to say, when the arm 36 is operated to release the roller 40 from the slot 32, the other arm swings in the same direction as the arm 36, and when the arm 35 is operated to cause the roller of the arm 37 to engage the slot 32, the arm 36 also swings in the same direction as the arm 35 under the action of its cam 42. v

The packet-wheel is brought to rest at intervals due to the intermittent motion imparted to it and one of these positions of rest is such that the box or receptacle 13 is immediately underneath, and in close proximity to, the lower end of the aforesaid tube or guide formed by the transfer channel 1 and fixed plate or support 14 so that a box or receptacle 13 forms a continuation of the said tube or guide. Above the said tube or guide is a plunger 43 (see Figs. 1, 6 and 8) having projections 45, which plunger is supported and guided in a boss 44 forming part of a bracket 15. This plunger 43 is capable of vertical movement so that at the proper time the plunger will enter the bag to such an extent as to permit the projections 45 coming into contact with the bag and so force it out of the tube or guide into the box or receptacle 13. Motion is transmitted to the plunger 43 from the auxiliary driving shaft 24, Figs. 1, 3 and 4, by the following means: Secured to the plunger 43 at any suitable point of its length is a pivot pin 46 (Fig. 1) which is connected to an oscillating arm 47 loosely mounted on a stationary shaft 48. The arm 47 is connected by a bridge piece 49 (Fig. 3) to a boss 50 also loose on the shaft 48 and formed on this boss is an arm 51 which, when operated, transmits its motion to the oscillating arm 47. The arm 51 is connected by a rod 52 to an oscillatinglever having two arms 53, 56, see Figs. 1, 3 and 4, and to the arm 53 is secured a roller 54 actuated by a cam 55 mounted on the shaft 24. The roller 54 is maintained in contact with the cam 55 by a spring 57 (Fig. 4), one end of which is secured to the arm 56 of the oscillating lever, the other end being secured to any suitable part of the circular guard 58, or to the framework. As soon as the aforesaid plunger 43 has been withdrawn out of the way of the bag which has been forced into the box or receptacle 13, a partial rotation is imparted to the packet-wheel 17 by the mechanism hereinbefore described and the next succeeding box or receptacle is brought into position immediately under the aforesaid tube or guide so as to receive a bag. One or more of these intermittent motions having been made, the said box or receptacle carrying a bag to be filled is brought immediately underneath one of a number of chutes forming part of the filling mechanism. The circular guard 58 consists of a suitably shaped plate or support arranged underneath the boxes or receptacles 13 so as to support the said bags and the said plate or support is arranged to cover therequisite distance along the circular path over which the aforesaid boxes or receptacles are caused to move by the intermittent movement of the packet-wheel.

To provide for the increased speed at which the apparatus according to my invention can be operated I arrange the filling .mechanism so that it is capable of moving with the packet-wheel during a certain period of partial rotation of the packetwheel. I preferably employ two chutes (but I do not limit myself to the use of two chutes) for the purpose of delivering material to orfilling the bags. The chutes illustrated generally in Figs. 1,3 and 9 and shown 1n detail in Figs. 10, 11, 12 and 13 and the said chutes 59 and 60 are mounted on a frame 61 having the arm 62 and the strut 63 pivotally connected to the framework 61 so as to permit of the chutes being more or less horizontal. The frame 61 is formed in one with a sleeve 64 mounted on the spindle 65 (Fig. 9), the lowerend of which is secured to the base plate 66, Fig. 5, of the apparatus. Horizontal and vertical movements are imparted to the frame 61 carrying the chutes 59, 60, by the arms 67 and 68 (Figs. 1, 3 and 9 respectively). The arm 67 is connected at one end to an arm 69, Figs. 3, 9 ,10 and 11, which is formed in one with the sleeve 64 and the said arm 67 is pivotally connected to a lever arm 70 (Fig. 1) pivoted at 80. The lever arm 70 has an extension 81 provided at its end with a roller 82 which is operated by a positively acting face cam 83 to produce the horizontal movement of the chutes 59, 60. 84 (Figs. 1 and 3) is a bracket carrying the pivot and the said bracket 84 is supported by the circular guard 58.

The vertical movement given to the chutes 59 and 60 is communicated to the said chutes from the peripheral cam 85, Fig. 1. This cam 85 actuates a lever 86 (Fig. 4) pivoted at 87 (Figs. 1, 3 and 4) carrying intermediate of its ends a roller 88 on which the cam 85 acts. The free end of the lever 86 is connected to a rod 87 whose upper end is pivoted to the arm 88 forming an extension of the arm 68. These two arms 68 and 88 operate as one lever so as to oscillate about the shaft 48. The roller 88 is kept in contact with the cam 85 by a spring, not shown, one end of which is connected to the lever or arm 86 and the other end to the frame at any suitable point. From the arm 68 the vertical motion thereof is communicated to the chutes by the action of a knocker arm 89, (Figs. 9", 12 and 13,) acting on the free end of a pivoted lever 90 having a roller and also having a bridge piece 91, which bridge piece carries the member 62 of the frame 61. The chutes are supported by a flange 92 formed on a forked bracket 93 which is pivotally connected to the arm 62 of the frame 61.

In order to insure that the material in the chutes shall be removed therefrom, I employ two plungers 94, 95, see Figs. 9, 10, 11 and 14, which are so supported and arranged above the parts 96, 97 of the chutes 59, 60 as to be capable of passing therethrough tocompletely remove the material.

Each plunger aforesaid is held apart by a distance piece 98 which has two forks 99, 100, which latter projects downward and these forks are connectedrespectively to a pivoted arm 101 and a link 102, which latter is pivoted bet-ween two links 103 to the frame 61, the lower ends of the links 103 being pivotally connected to the lever arm The upper ends of the links 103 are pivotally supported by a'lever having three arms 104, 104 and "105, the two former arms 104, 104 being connected by a bridge piece 106 and the arm 105 being provided with a roller 107 which bears against a knocker arm 108. The knocker arm 108, see Figs. 1, 9, 10, 11, 14 and 15, is formed on a lever having two arms 109, 110, the said lever being pivoted at 48 and adapted to oscillate thereon. Motion is transmitted to the arm 110 from thecam 111 through the rod 112 which is connected to an oscillating arm 113 pivoted on 87 and carrying a roller 114 which is actuated by the cam 111. The roller 114 is maintained in contact with the cam 111 by a spring connected to the said arm and to the frame of the apparatus. Under this construction and arrangement it will be seen that the plungers 94, are first swung into a vertical position and are then caused to descend so as to eject the material from the chutes.

The chutes hereinbefore described can be of any desired length and may consist of tubes or channels 96, 97 of any suitable section which widen out at their ends to constitute funnels 59, 60, into which the required amount of material is supplied by any suitable means such as by hand, or from weighing or measuring apparatus. The lower ends of the chutes 59, 60 are secured at a distance from each other corresponding to that between the boxes or receptacles 13 on the packet wheel 17. The horizontal or oscillatory movement in a horizontal plane in one direction is uniform with and occurs at the same time as the necessary intermittent rotating motion of the packet wheel 17 and the chutes can be caused to move vertically by means of the mechanism hereinbefore described so that the lower ends of the chutes can be lowered into or lifted out of the upper ends of the bags supplied to the boxes or receptacles 13.

The filling chutes 59, 60 and the plungers 94, 95 therein are operated at half the speed of the packet-wheel the necessary reduction in speed being obtained by a gear wheel 115, Fig. 4, on the sleeve 116 mounted on the auxiliary shaft 10. This wheel 115 gears with the wheel 117 secured to the shaft 24, which latter shaft 24 is driven from the driving sleeve 16. The reduction in speed affects also the cams 83, 111 and 85 which as already described are secured on the sleeve 116 mounted on the shaft 10. From the foregoing it will be obvious that the plungers 94, 95 which operate on the chutes 59, 60 move with the said chutes in their horizontal movement, but are independent in their vertical movements of the motion of the chutes. 4

It is to be understood that the filling means rotate with the carrier through an arc corresponding to the distance between two bags, and during this movement two bags are filled. The chutes then rise and make a return movement through an arc corresponding to the distance between two bags while the carrier wheel moves through a like are in the reverse (z'. e. the forward) direction, the carrier wheel intermittently moving through such arcs and the chutes being so operated that at each alternate movement of the carrier wheel the chutes, in two bags,

move with the carrier wheel and fill the bags, and at each other alternate forward movement of the carrier wheel, the chutes (having risen from the bags)'move back through a like are in the reverse direction, when it will be understood, they are in position to descend into the two bags which come next in series to the bags last filled, as during this backward movement of the chutes the carrier has moved forward through a like are.

By the statement above made that the filling chutes operate at half the speed of the packet wheel, is to be understood that when the wheel moves through two arcs equal to the distance between ba and bag, the chutes move through only half that forward movement, that is, through the distance of one such arc, as the chutes, during the movement through the second are, are moving through a like are in the reverse, or backward, direction. Of course the fixed plate 1 1 is not part of the transfer channel 1 and does not move with it. When the bag is in a vertical position the plate 14 forms a side of the channel.

The mode of operation of the apparatus is 'as follows: Assuming a bag to have been placed in the transfer channel 1 when in the horizontal position, the driving sleeve 16 is clutched to the driving pulley (not shown) which starts the series of operations. When the apparatus is started, the transfer channel is caused to rotate from the horizontal position into the vertical position by the ac- .tion of the racks 4. and 5 and connections thereto. The plunger 43 now operates to force the bag out of the gpide formed by the transfer channel into a ox or receptacle 13 on the packet-wheel 17. The arrangement of the gearing between the driving sleeve and packet-wheel is such as to causethe said packet-wheel 17 to make three separate partial rotationswhich carries the bag to a position underneath thechute 60. In the interim a number of bags are forced in succession into their respective boxes or receptacles, so that when the three partial rotations of the packet wheel have been made, there are two bags in position under the chutes 59, 60, that is, one under each chute.

. The chutes now descend and enter the bags,

another partial rotation, the chutes 59,

which in the meantime are clear of the boxes or receptacles, l3, rotate in the opposite direction to the wheel and subsequently regain their initial position.

What I claim is- 1. An apparatus for filling bags, having a rotary bag carrier, and filling means arranged concentrically therewith and comprising a filling chute, means for moving the same substantially vertically into and out of filling position with relation to a bag on said carrier, and means for rotating said chute with the carrier while in filling position and for rotating it in the opposite direction after its withdrawal from filling position'.

2. An apparatus for filling bags, having a bag carrier, means for imparting intermittent rotary motion thereto, and filling means arranged concentrically therewith and comprising a filling chute, means for moving the same downward into filling position with relation to a bag on said carrier while the latter is halted, means for rotating said chute with said carrier in filling position, and means for lifting said chute from filling position while halted after partial rotation, substantially as described.

3. An apparatus for filling bags, having a bag carrier for supporting a plurality of bags, means for imparting rotary motion thereto, and filling means arranged concentrically therewith and comprising a plurality of filling chutes, means for moving the same downward into filling position with relation to a plurality of bags on'said carrier, means for rotating said chutes with the carrier while in filling position and means for lifting and returning the same to original position.

4. An apparatus for filling bags, having a bag carrier for supporting a plurality of bags, means for imparting intermittent rotation thereto, and filling means arranged concentrically therewith and comprising a plurality of filling chutes, means for moving the same downward into filling position with relation to a plurality of bags on said carrier while the latter is in halted position,

after partial rotation and means for returnnation with a plunger working in said chute to clean the same after it has reached its lifting position, substantially as described.

, In testimony whereof I have signed my 15 name to this specification in the presence of two subscribing witnesses.
